Melt glue stick

The classic way to quickly attach tops. These glue sticks can be cut with a sharp thin knife. Cut a slice into small stips and put some strips in the tube of the tops. Then hold it briefly in the burner flame (hold it with needle nose pliers ..;-) then press directly on the top. Is almost immediately stuck, to align again briefly heat. Roughen the top and possibly also the inside of the tube. Works well and quickly, but attaching with thixopoxy glue is more reliable at high heat.. Thixopoxy is more difficult to release if the tops needs to be replaced.
